Effectiveness
Nexplanon and Implanon are a type of long-acting reversible contraception, which has been shown to be the most effective form of birth control available. The failure rate of Implanon is .05% for both perfect use and typical use because the method requires no user action after insertion. Prospective follow-up studies of Implanon, which include over 2,467 women-years of exposure, have found no pregnancies. Other studies have found some failures with this method, some attributed to failures of the method itself and others to improper placement, drug interactions, or conception prior to method insertion.
In comparison, tubal sterilization has a failure rate of 0.5% and IUDs have a failure rate of 0.2-0.8%. These statistics suggest that Implanon and Nexplanon almost ten times more effective at preventing pregnancy than tubal sterilization. Also, tubal sterilization is permanent, whereas the subdermal implant must be replaced every three years. On the other hand, Nexplanon or Implanon is completely reversible, while sterilization is permanent and cannot be reversed.
